Abstract
Abstract This invention relates to ink film transfer and particularly to printing on surfaces by offset and direct printing techniques with an immediately dry image transfer of controlled thickness. When these techniques are employed in direct printing, the die or printing member is not inked directly with a fluent ink, but rather with a substantially dry ink-film, whereby small legend characters are not smothered or ''''filled-up.
